The problem is making the first headstock spindle without another
lathe. Once you have it you can machine a better one.

In my case someone would likely offer me a good lathe cheap *after*
seeing the one I struggled to make.

I wouldn't attempt this without access to another lathe, unless someone made
it a group or club project and made the necessary machined parts available
for a reasonable price.

I think it could be achieved starting with a simple machine that's
adjusted into place. For example my dead-center lathe could bore the
headstock pipe for your cast concrete one. Slide the headstock down
the ways over a long fixed boring bar.

The practical application is temporary oversized equipment to
recondition old worn machines. I'd like to rig up a milling head with
enough X and Y travel to clean up the ways of my surface grinder. It
only needs to slide along one axis while cutting, and can rest on
parallels for the other axis.
